In this issue, JAXA introduces the three largest of the 3,400 large and small islands that compose the Republic of Korea. Jin-do is located in Jindo County, Jeollanam-do (South Jeolla) Province, at the southwestern end of the Koran Peninsula. The island is separated from the Peninsula by the 300m-wide Myeongnyang (also known as Uldulmok) Strait and is connected by the twin 484m-long Jindo Bridges completed in 1984 and 2005. The fast current and large whirlpools, similar to those of Akashi strait in Japan, make ship passage difficult. You can see the drift of tide at Jindo Bridge in the figure. It takes six hours from Seoul and six and a half hours from Busan by bus to the bus terminal in central Jin-do, Jindo-Eup. It also takes a half hour to Hoedong-ri by bus. A separated family meet again on the mystic road in an old Korean tale. Japanese singer Yoshimi Tendo sang the song "Jindo Story," based on such meeting. This made Jindo famous in Japan thereafter. Figure 2 presents a close-up of Hoedong-ri and Modo-ri. It is not Spring Tide day, but the Mystic Sea Road is faintly visible. Geoje-do, South Korea (kmz, 4.00MB, Low Resolution) as seen on Google Earth. Figure 3 presents an image of the second largest island in the Republic of Korea, Geoje-do Island (400km square; the same area as Japanese Nagasaki City). Geoje-do is an attractive island with a deeply indented coastline and massive mountains. Tourists can enjoy both the mountains and the sea, and enjoy the beautiful nature of the beaches along the coastline and Haegeumgang from east coast to south coast. It is also a major hub of the shipbuilding industry in Korea. It is said that the Sun of Geoje-do rises from a shipyard and sets in a shipyard because Daewoo Shipbuilding and Marine Engineering Co. is located at Okpo in the east and Samsung Heavy Industries Geoje Shipyard is located at Gohyeon in the west. The 800m-wide Gyeonnaeryang Strait separates Geoje-do from the Korean Peninsula, but Geoje Bridge and other bridges connect with the peninsula. It takes three hours from Busan by car. The Korean remake movie, "My girl and I/ Parang love," from the famous Japanese novel, drama and movie, "Socrates in love" was shot on this island. Oedo Island is the nearest island to Japan,  and is not far from Japanese Tsushima Island. Figure 4 depicts the largest Island (1,850km square; larger than Okinawa Island and the same area as Osaka Prefecture) in the Republic of Korea, Cheju-do or Jeju-do. The island is located in southernmost Korea, but at the same latitude as Nagasaki or Kochi. It is 100km south of the Korean Peninsula and 180km from Goto Islands in Nagasaki. Jeju-do is a rare volcanic island in Korea. Mt. Halla in the center of the island is 1,950m above sea level and last erupted in the 11th century. The Sungsan Ilchulbong or Sunrise Peak on the eastern end of the island is a 5,000-year-old tuff cone (600m in diameter) in a circular depression. It is covered by grass and is famous for its beautiful sunrises. The Geomunoreum lava tube system, including Geomunoreum, Manjangul, Gimnyeonggul and Yongcheondonggul, is located on the northeastern part of the island. With a length of 13,422m, Manjangul is the longest lava tube in the world. These spots were registered on the World Heritage list of the United Nations Educational, Scientific and Cultural Organization (UNESCO) as Jeju Volcanic Island and Lava Tubes in 2007. On the north of the island is Jeju City, and on the south is Seogwipo City. Seogwipo City is the southern end of Korea. In addition to these two cities, Jeju-do also had Bukjeju-gun and Namjeju-gun in the eastern and western parts of the island as enclaves. The Jungmun district in Seogwipo City is one of the most popular tourist resort areas in the Republic of Korea and has many luxury hotels with beautiful white beaches and cliffs. Two settings for "The Story of the First Kingâs Four Gods," a Korean TV historical fantasy drama based on old Korean myths, are located near Manjangul cave on the eastern part of the island. Figure 5 depicts the locations of the three Korean islands described in this issue. AVNIR-2 has four observation bands. Figures 1 to 4 were produced by assigning red to Band 3 (610 to 690nm), green to Band 2 (520 to 600nm), and blue to Band 1 (420 to 500nm). The resulting images have natural coloring as if seen by the naked eye. Thus, the following colors designate ground objects.
